Question

If the potential differences across three resistances connected in parallel are V1,V2&V3 the potential difference across the total resistance V =
I Want with explenation

Answer 1

Answer:

the answer is V potential. No addition no subtraction. V is only V.

Explanation:

The Given resistance combination is parallel. So the potential drop in each resistor is same.

Step 1.

Get the resultant resistance by using the formula

1/R = 1/R1 + 1/R2 + 1/R3

Step 2.

There should be Current given to you. So find it. If a battery is given with it's Internal Resistance use Kirchoff's Voltage Law.

Step 3.

Use Ohm's Law

V= I R. Mind this that Potential drop is same across n Resistors in parallel so

You can derive from this that

V= V1 = V2 = V3
